1. A base station, comprising:
a transceiver configured to:
transmit configuration information indicating one of a maximum transmission block size (TBS) or a maximum modulation and coding scheme (MCS) for one of a physical uplink shared channel (PUSCH) transmission or a physical downlink shared channel (PDSCH) reception, wherein the maximum TBS or the maximum MCS is configured based on a mapping between the maximum TBS or the maximum MCS and one of a plurality of defined non-terrestrial network (NTN) modes, the NTN modes each corresponding to a distance between the base station and a terminal, and
transmit a signal indicating whether the PUSCH transmission or PDSCH reception uses a default MCS or an MCS that is determined based on at least the configured maximum MCS,
wherein the PUSCH is received or the PDSCH is transmitted based on the signal.
